The SICK NANS3-AAAZ30AN1 is a compact through-beam photoelectric sensor designed for reliable object detection in industrial automation. It consists of a paired transmitter and receiver: the transmitter emits a focused red light beam, and the receiver detects interruptions of this beam. This design ensures high accuracy and stability, even in challenging environments. With its miniature size and IP67 protection, it is ideal for applications in packaging, material handling, and assembly automation where space is limited.
